6 Claims. (CI. 20-42) This invention relates in general to improvements in windows, and more specifically to an improved window which includes sliding and swinging sashes and is an improvement on my Patent No. 2,613,928, issued October 14, 1952.

The primary object of this invention is to provide an improved window construction which includes an extremely simple operating means for slide bars to which sashes are mounted for sliding and swinging movement.

Another object of this invention is to provide an improved window construction which includes a simple slide operating means, the window construction being of such a nature whereby the operating means are concealed within the confines of the window when the sashes are in their closed positions.

A further object of this invention is to provide an improved operating means for a window, the operating means including slide bars which are operated in response to rotation of operating shafts, the operating shafts being provided with coacting follower blocks carried by the slide bars for movement along the operating shafts in response to rotation thereof.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of the improved window construction which is the subject of this invention and shows the same mounted in a wall of a building, the window construction being viewed from the interior of the building and having its sashes in their open positions;

Figure 2 is a fragmentary front elevational view of the window of Figure l on a larger scale with the sashes in closed positions and portions of the window frame and wall being broken away and shown in section in order to clearly illustrate the relationship of various elements of the operating means for the sashes, an intermediate portion of the window being omitted;

Figure 3 is a transverse vertical sectional view taken substantially upon the plane indicated by the section line 33 of Figure l and shows the relationship of the various elements of the operating means when the sashes are in their closed positions, the sashes being shown in their open positions by dotted lines, an intermediate portion of the window construction being omitted and the wall of the building being omitted for purposes of clarity;

Figure 4 is an enlarged fragmentary perspective view of the lower portion of the window construction of Figure l as viewed from the outside, the building wall being omitted and portions of the window frame and sash being broken away and shown in section in order to clearly illustrate the details of the operating means for the window;

Figure 5 is a transverse horizontal sectional view taken substantially upon the plane indicated by the section line 55 of Figure 3 and shows the manner in which slide bars of the operating means are mounted for vertical sliding movement, portions of the window frame being broken away and shown in section in order to clearly illustrate the relationship of means for simultaneously sliding both slide bars, an intermediate portion of the window being omitted;

Figure 6 is an enlarged fragmentary horizontal sectional view taken substantially upon the plane indicated by the section line 66 of Figure 3 and shows the arrangement of drive means in the bottom portion of the window frame for simultaneously rotating both operating shafts;

Figure 7 is a fragmentary vertical sectional view taken substantially upon the plane indicated by the section line 7-7 of Figure 6 and further shows the construction of the drive means, portions of the drive means being broken away and shown in section in order to clearly illustrate the manner in which they are secured together; and

Figure 8 is an enlarged fragmentary sectional view taken substantially upon the plane indicated by the section line 8-8 of Figure 4 and shows the general crosssection of one of the slide bars and the relationship of the associated follower block thereto, also being shown in the manner in which a key carried by the follower coacts with the operating shaft associated with the follower block, or vice versa.

Referring now to the drawings in detail, it will be seen that the window construction, which is the subject of this invention, includes a window frame which is referred to in general by the reference numeral 10. The window frame 10 is seated in a building wall 12 andincludes a pair of spaced vertical frame members 14 and 16 which are connected together at their lower ends by a bottom horizontal frame member 18 and at their upper ends by an upper horizontal frame member 20.

lt will be understood that the frame: members 14, 16, 18 and 20 of the window frame 10 are similar in crosssection and that each of the frame members includes a transversely extending web 22 which is intended to engage an edge of the building wall 12 forming a boundary of the opening in which the window frame 10 is seated. Formed integrally with the web 22 and extending outwardly therefrom is a pair of spaced parallel flanges 24 and 26. The flanges 24 and 26 are disposed at the front and rear edges of the web 22 and are so spaced as to engage surfaces of the wall 12. Also formed integrally with the web 22 and extending inwardly as extensions of the flanges 24 and 26 are rear and front flanges 28 and 30, respectively, The rear flange 28 extends further inwardly than the front flange 30 and terminates in a forwardly extending flange 32, as is best illustrated in Figure 1.

Carried by the window frame 10 for both vertically sliding and swinging movement is a plurality of substantially identical or otherwise sashes which are referred to in general by the reference numeral 34. Each of the sashes 34 includes a sash frame which is rectangular in outline and which is referred to in general by the reference numeral 36. Each sash frame 36 includes a pair of spaced vertical sash frame members 38 which are connected at their lower ends by a lower horizontal sash frame member 40 and at their upper ends by an upper horizontal sash frame member 42. Carried by the sash frame 36 is a suitable glazing 43.

Disposed within the confines of the vertical frame members 14 and 16 are slide bars which are referred to in general by the reference numeral 44. Each of the slide bars is angular in cross-section and includes an inwardly directed web 46 which has formed integrally with the edges thereof outwardly directed flanges 48. The flanges 48 terminate at their outer edges in forwardly and rearwardly directed flanges 50. As is best illustrated in Figures 2 and 5, carried by the webs :22 of the vertical frame members 14 and 16 in vertically spaced relation are rollers 52. Each of the rollers 52 is mounted on a ii pin 54 carried by its associated web 22 and projecting inwardly therefrom. The roller 52 is spaced from its associated web 22 by a spacer 56 carried by the pin 54 intermediate the roller 52 and its web 22. As is best illustrated in Figure 5, the rollers 52 engage the opposed faces of the flanges 48 of each slide bar 44 adjacent the associated web 46 so as to control movement of the slide bar 44 transversely of the window frame 19. Also, the flanges 56 of each slide bar 44 are adapted to engage the inner surface of an associated web 22 so as to prevent outward movement of the slide bar 44.

Carried by each of the vertical sash frame members 38 adjacent their upper ends are inverted generally J-shaped sash hangers 58. The sash hangers 58 are secured to the outer surfaces of their associated vertical sash frame members 38 by suitable fasteners 69 and have their upper ends pivotally connected to the inner surfaces of the webs 46 by pivot pins 62. It will be understood that there is one hanger 58 on each side of each sash 36.

Pivotally connected to each of the vertical sash frame members 33 intermediate its upper and lower ends by pivot pin 64 is an arm 66. The lower end of the arm 66 is pivotally connected by a pivot pin 68 to an angle bracket 70 which is suitably secured by the flange 28 of an associated vertical frame member of the frame 10.

Referring now to Figures 6 and 7 in particular, it will be seen that there are illustrated operating means for causing movement of the sashes 34 from open to closed positions and vice versa. These operating means include a horizontal shaft 72 which is mounted within the confines of the lower horizontal frame member 18. The shaft 72 is provided with bores 74 in opposite ends thereof in which are received relatively short shafts 76. The short shafts 76 have their inner ends secured within their respective bores 74 by pins 78. The shafts 76 are suitably journaled in bearing blocks 84} extending upwardly from the web 22 of the lower horizontal frame member 18. Rem ovably carried by the outer end of each of the shafts 76 is a bevel gear 82. The bevel gear 82 of each shaft 76 is disposed in a vertical plane.

Secured to the web 22 of the lower horizontal frame member 18 in vertical alignment with the interior of the vertical frame member 14 is a suitable bearing 84. The bearing 84 has received therein the lower end of an operating shaft 86. The operating shaft 86 has removably secured thereto within the confines of both the lower horizontal frame member 18 and the vertical frame member 14 a horizontally disposed bevel gear 38. The bevel gear 88 is intermeshed with its associated bevel. gear 82 and is driven in response to rotation of the shaft 72.

Carried by the web of the lower horizontal frame member 18 in vertical alignment with the interior of the vertical frame member 16 is a suitable bearing member 90. The bearing member 90 has rotatably journaled in the lower end thereof an operating shaft 92. The operating shaft 92 has removably secured to the lower portion thereof a horizontal bevel gear 94 which is engaged with its associated vertical bevel gear 82.

Carried by the web 22 of the vertical frame member 16 is a pair of mounting brackets 96, as is best illustrated in Figure 6. The mounting brackets 96 have disposed therein horizontally aligned bores in which is received an operating crank 98. The operating crank 98 is provided on the rear end thereof with a handle 100 to facilitate rotation thereof. Carried by the operating crank 98 intermediate the mounting brackets 96 is a worm gear 102 which is engaged with a gear 104 removably secured to the operating shaft 92 above the bevel gear 94.

From the foregoing description of the Operating means, it will be seen that when the crank 98 is rotated, the operating shaft 92 will also be caused to rotate. This results in the rotation of the shaft 72 which in turn causes the rotation of the operating shaft 86. It will be understood that'the operating shafts 86 and 92 will H t te simultaneously at the same speed.

Referring now to Figures 4 and 8 in particular, it will be seen that the lower end of the slide bar 44 carried by the vertical frame member 16 has mounted therein a rectangular follower block MP6. The follower block 106 is in vertical alignment with the'vertieal axis of the operating shaft 92 and has formed therein a vertically extending bore 108 in which is received the operating rod 92. The follower block 106 is secured in the lower end of its associated slide bar 44 by a pair of vertically spaced fasteners 110. The operating shaft 92 is provided with a spiral groove 112 in which is received a longitudinally spiralled key 113 formed integrally with the follower block and which extends into the bore 108. Thus, it will be seen that when the operating shaft 92 is rotated, the follower block 106, which is held stationary by the associated slide bar 44, will move along the operating bar 92 to cause vertical sliding of the slide bar 44 carried by the vertical frame member 16. The slide bar 44 carried by the vertical frame member 14 is provided with a similar follower block 106. The follower block carried by the slide bar'44 of the vertical frame member 14 is secured to that slide bar in the same manner as is described above with respect to the follower block 106, and the key thereof is received in a spiral groove 114 in the operating shaft 86. Thus, it will be seen that the two slide bars 44 will move vertically in their associated vertical frame members at the same rate. It is to be understood that, if desired, the keys may be carried by the operating shafts and the grooves formed in the follower blocks.

Assuming that the sashes 36 are in their closed positions, upon downward movement of the slide bars 44, the upper portions of the sashes 34 together with their hangers 58 will move downwardly. Inasmuch as the arms 66 are pivotally connected at opposite ends to the sashes 34 and their respective vertical frame members, it will be seen that downward movement of the upper portions of the sashes 34 will result in outward swinging of such sashes tothe positions illustrated in Figures 1 and 4-.

It will be understood that the vertical sash frame members 38have their outer surfaces spaced apart greater than the spacing of the inner surfaces of the flanges 32 of the vertical frame members 14 and 16. This results in the rear surfaces of the vertical frame members 38 engaging the forward edges of the flanges 32 when the sashes 34 are in their closed positions to effect the sealing of the sashes 34 relative to the window frame 10.

The vertical sash frame members 38 are also provided with outwardly extending flanges at their forward edges. The flanges 120 overlie the flanges 30 of the vertical frame members 14 and 16 to further effect a seal between the-sides of the sashes 34 and the window frame 10.

The lower horizontal sash frame member 40 of the lowermost sash 34 is provided with a depending flange 122 which overlies the flange 30 of the lower horizontal frame member 18. This'effects a seal between the lowermost sash 34 and the lower horizontal frame member 18 of the window frame10.

The upper horizontal sash frame member 42 of each of the sashes 30 is-provided with an upwardly projecting flange 124. The flange 124 of the uppermost sash 34 engages under the depending flange 30 of the upper horizontal frame member 20 which is provided with an offset lower'lip portion 126, as is best illustrated in Figure 3. Also, the lower horizontal sash frame members 40 of all of the upper sashes 34 are provided with outwardly offset flanges 128 which engage over the flanges 124 along the upper edges of the next lower sashes 34.

From the above description of the relationship of the sashes 34 relative to each other and to the window frame 10, it will be seen that not only are the sashes 34 sealed with respect to each other and to the window frame 10 when in their closed positions, but also the sashes 34 close the open portions of the frame members of the window frame 10 so as to conceal their operating means when the sashes 34 are in their closed positions.

It will be noted that through the use of a simple operating shaft being provided with a spiral groove and a follower, rotary motion of an operating shaft may be converted into vertical sliding motion of a slide bar. This simple drive mechanism not only permits the formation of economically feasible drive means, but also permits the drive means to be mounted within a relatively small space so as to provide a window which is pleasing in appearance.

From the foregoing, the construction and operation of the device will be readily understood and further explana tion is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
